BOWLING PIN.

This invention relates to bowling pins and it is especially useful inthose pins which are made of a plastic composition in the form of ahollow shell.

It has been found in practice that bowling pins made of plasticcomposition in the form of a hollow shell are liable to break at theneck because of the bending strains to which the neck is subjected underthe impact of the ball against the body of the pin and also from theblows to which the body and the head are subjected in the bowling alleypit.

The object of my invention is to reinforce and strengthen the neck ofthe pin so that it will satisfactorily resist the bending strains towhich the neck of the pin is subjected in actual use, and to do this ina manner and by use of means which will not add materially to the costof manufacture.

In the accompanying drawings have illustrated the invention in a pinmade of plastic composition in a simple form, and referring thereto-Fig. 1 is a vertical central sectional view.

Fig. 2 is a transverse sectional view on the line 22 of Fig. 1., and

Fig. 3 is a detail perspective view of one of the reinforcing members.

Referring to the drawings, the pin comprises a shell made of a plasticcomposition, such as a hard rubber compound, and having a body 4-,, aneck 5 and a head 6. I have shown this shell in a simple form toillustrate the adaptation of my invention, but it will be understoodthat the invention can be employed in any form of hollow compositionshell to which it is or may be adapted. A plurality of reinforcingstrips or members 7 are embedded in the neck of the shell on the innersurface thereof and preferably extend throughout the length of the neckand. into the body and head of the pin. I prefer to make these membersor strips of resilient strengthening and reinforcing material, and forthis purpose I have found spring metal satisfactory because it can bemade thin, light in weight and easily applied. The members may besecured to the shell in a suitable manner as by providing the memberswith projections or barbs. 8 and turning over the-ends 9 so that all of16, 1925. Serial N0. 9,371.

the projections will be embedded in the neck of the shell as shown inFig. i.

These members or strips reinforce and strengthen the neck of the pin toresist the strains to which the neck is subjected in the use of thepins. As many of the members may be provided as found to be necessary ordesirable and they can be made narrower or wider than those shown in thedrawings, as good practice may require. However, i have found that fourmembers of substantially the size and shape illustrated answer thepurpose satisfactorily. Not only do these members resist the strains towhich the neck of the pin is subjected in use, but they strengthen andreinforce the neck of the pin generally and in that Way prolong the lifeof the pin.

I am aware that changes may be made in the construction and arrangementof my invention, some of which have been hereinbefore indicated, andIreserve the right to make all such changes as fairly fall within thescope of the following claims:

I claim:

1. A bowling pin comprising a shell made of plastic composition andhaving spaced reinforcing members embedded in the neck lengthwisethereof.

2. A bowling pin comprising a shell made of plastic composition andhaving a plurality of relatively narrow elongated strengthening andreinforcing members spaced apart and embedded in the neck thereof.

3. A bowling pin comprising a shell made of plastic composition andhaving a plurality of relatively narrow and resilient metal membersembedded in the inner surf-ace, of the neck thereof to strengthen andreinforce the neck.

4. A bowling pin comprising a shell made of plastic composition, and a,plurality of strengthening and reinforcing members having projectionsthereon embedded in the inner surface of the neck thereof.

5. A bowling pin comprising a shell made of plastic composition, and aplurality of strengthening and reinforcing metal members extendingthroughout the neck thereof and beyond to the body and to the head ofthe pin and having projections embedded in the inner surface of theneck.
